（1）  The logic here and  【39： The third chapter ： Developing a pass service ：22： Log out & Log off the session ;】 The practice in is exactly the same ; It's just , Delete cookie The logic of , We drew out a method alone ; 

（2） Here we need to pay attention to a development time , Suggested points to follow ：

          ●  We are facing cookie When setting the value in , All of them adopt 【URLEncoder.encode( String to be encoded , “UTF-8“);】 It's encoded ; namely , here cookie The values in are in the above encoded format ;

          ●  that , We are revising cookie When it's worth , This value , It's best to use 【URLEncoder.encode( String to be encoded , “UTF-8“);】 Encoding ;

          ●  This helps , Avoid many possible 、 Strange questions ;（ Especially in the production environment ）

          ●  For this point , I feel a little bit ; but , In fact, it is not very clear , Not thoroughly understood ;

First, the whole situation install Look at the whole project ; then , Start the front-end project ; Remember to use SwitchHost Open virtual domain name mapping ; start-up 【admin】 The main startup class of the management service ;
